Re: Crucial SSD not recognised by Acronis True Image for Crucial

If the SSD is connected externally, then perhaps the USB adapter/dock/enclosure is blocking the command Acronis uses to request the identity of the SSD. If you do not have another brand adapter, then I would suggest creating a bootable Acronis USB drive (See section 6.1 on beginning on page 56 of the Acronis for Crucial User Guide for instructions). Then install the new SSD internally and connect your original drive externally. During system POST access your BIOS/UEFI boot menu and select the Acronis USB boot drive. Or you can try using some other software to clone your drive.
